CHARLES PAY, OF PROVIDENCE, RHODE ISLAND.

SCOOP-BUCKET FOR DREDGING PURPOSES.

Specification of Letters Patent.

Patented April 9, 190?l Application filed January 21.1907. Serial No. 353.391.

To @ZZ whom t may concern:

Be it known that I, CHARLES PAY, a citizen of the United States, and a resident of the city of Providence, in the county of Providence, State of Rhode Island, have invented certain new `and useful Improvements in Scoop-Buckets for Dredging Purposes, of which the following is a specification.

The object of my invention is to provide this class of bucket with a double door, arranged to open inwardly of the bucket-body when coming in contact with the water, in order to reduce the concussion caused by the great lweight of the bucket when the latter strikes the water, and to permit the hastening of the bucket to themud material to be lifted.

A further object of my invention is to provide meansfor firmly securing the bucketbody to its handle or post.

My invention consists of the novel con.-

struction, arrangement, and combination of parts, as hereinafter described, and speciiically set forth in the claims.

Figure l is a side elevation of the scoopbucket as closed and in operative position to receive its load. Fig. 2 represents the' discharge end of the bucket, showing the parts embodying my improvement and corresponding to the position of parts shown in Fig. l. Fig. 3 is a sectional view of the bucket, showing the position the doors assume when the bucket strikes the water. Fig. 4 is a sectional view of the bucket in vertical position and showing the relation of parts as when the bucket-load is discharged. Fig. 5 is a top plan section taken in line 5 5 of Fig. 2. Fig. 6 illustrates my improved means of securing the bucket-body to its handle or post. Fig. 7 is a sectional view of one pair of the brace connections for the bucket-body and its post, and Fig. 8 shows the manner of securing a brace connection to a iixed plate of the bucket-post.

Like reference characters indicate like parts in the several views of the drawings.

Referring to Figs. 1 and 2, a designates the body or shell of the scoop-bucket, which is of the conventional rectangular form in crosssection, said bucket having its top a secured by braces l) b to the end of the bucket handle or post c, which receives power to force the bucket into the mud Vmaterial to be lifted,

the prongs d secured to the bottom ai* of the bucket to embed in said material, the bail e pivoted at f to the sides a3 a3 of the bucket and having a hoist-chain connection g, which receives power to lift the bucket to a vertical position after receiving its load, and a swinging door 7L pivoted at points c' t to the top of the bucket.

All aforesaid parts as commonly constructed and arranged in this class of bucket, with the exception that I design the door h to close about one-half the discharge end of the bucket.

I will now proceed to explain the parts embodying my improvement.

y' represents a yoke member, whose lower portion extends in front of the discharge end of the bucket, near to its bottom a2, and about midway of the discharge end of the bucket said yoke member straddles over and is pivotally connected to the sides a3 of the bucket, as at points 7c if, and said yoke mem- :ber is provided with circular openings Z4 through its sides and arranged opposite each other, so as to form journal-bearings, whose axial centers come beyond the free end portion of the door h when the latter is Within the discharge end of the bucket.

A second door m has an axle-shaft m secured thereto and whose ends are mounted in the journal-bearings Z of the yoke member y'. This second door mis of a size to close the remaining portion of the discharge end of the bucket that is left by the door h, and said' second door overlaps the edge of the free end portion of the door h when both doors are in a closed position Within the discharge end of the bucket, as shown in Fig. l. On the yoke is secured a truss n, which rests upon the outer surface of the door fm and arv ranged to support a device to operate in locking both said doors 7L m after they close the discharge end of the bucket. This device comprises a latch-bar o, which is slidable through the truss or support extension n and yoke y', respectively, and said bar is arranged to enter an opening p, formed in a block which is secured to the bottom of the bucket. The opposite end of the bar o is connected to a trip-lever r, which has one end pivoted on the truss or support extension n, as at s, and at its other end connected to'a pull-chain t.-

- On the bucket handle or post c is secured the usual toothed rack, (not shown,) which meshes with a power-driven gear, whereby the bucket is caused to move to the position desired.

Prior to the bucket striking the water the IOO IIO

two doors are allowed to swing within the bucket-shell, so as to allow the latch-bar to fall by gravity within the opening p of the block g, and thus securing said doors in a locked position within the bucket-shell. The

bucket is then ready to fall to the river mud bottom, and the moment the bucket strikes the water the two doors, which previously closedits discharged end, simultaneously open :o inwardly oi thehbucket approximately to the position shown in Fig. 3, and thereby allowing the bucket-shell to fall rapidly through the water to the bed of the river. After the bucket has received its load ol mud material I and is carried to the position shown in Fig. 4 the chain t is pulled upon to withdrawthe bar o, which as soon as released from its locked position permits both doors. to swing outwardly from the bucket-shell, and there- 2o by cause the discharge of mud material.

In order to limit the inward swing of the door m, a stud is secured in the side of the bucket-body, as at a point u in Fig. 3, and thus forming a stop for said door.

2 5 Having described my improved door arrangement, I will now explain my improved structure for securing the bucket-body to its handle or post.

Referring to Fig. 6, a brace connection o 3o extends from each corner of the top portion of the bucket-body to the post c, and each brace connection consists of two members o and 02, as shown in Fig. 7. The brace member c has an eye o3 formed at one end and 55 provided with an opening to receive the Vpin w, which is secured in the side of the bucket-v body, and said member o has its opposite end provided with an vopening to receive a rivet w. The brace member 'u2 has one end provided with an opening to receive aremovable bolt wz, and its opposite end provided with a slotted opening, as at o", to receive a wedge-key and gib respectively. Headplates y are secured in a iixed position upon each side of the post c, each plate having an integral hub fy, provided with a bore to receive therethrough the slotted end portion of the brace member o2. The inner ends of each pair of brace members 'u' v2 are secured 5o between link-plates 2 z by the rivet w and the bolt wg, which pass, through said plates.

Each plate z is provided with openings z',

that register vopposite each other and arranged to permit of .positioning the brace members fo v2 by the bolt @U2 in securing the bucket-body to its post. As the wedge-key is driven in placqit bears against the upper face of the hub y and the lower edge of the gib x, which latte'r rests against the shoulder formed by the upper end of the slot v4. Thus said key causes a pull upon the brace members o 02, and thereby holds the bucket-body rigidly secured to its post` It is therefore apparent that should the bucket-body become loose upon its post all that is necessary is to simply drive the ke s x farther in place to again secure the buc et firmly in position.

In case of breakage of any of the four brace connections o the bolt 102 may be easily withdrawn and each member o v2 readily got 7o at lor repair.

Thus 1t is seen that by my construction of double-door arrangement, as described, I am enabled to greatly overcome the shock or concussion caused by the great weight of the bucket in striking the water and to permit a rapid descent of the bucket to the river mud bottom. Furthermore, my structure for iirmly securing the bucket-body to its post l readily permits of disconnecting any of its 8o brace members when in need of repair.

What I claim, and desire to secure by Letters Patent, is-
